3 Claims. 1

The invention relates to improvements in locking-bolt operatingstructures and particularly to an assembly of this character of flushpanel construction, for use with a closure having a recess breaking itssurface. By flush panel construction is meant an assembly in which theentire means for actuating a locking bolt lie substantially between theplanes defining the outer and inner faces of the closure. Preferably,the means serving as the actuating handle or finger pullpiece aredisposed substantially flush with the adjacent outer face of theclosure. Such type of locking-bolt operating structure is of highlyimportant advantage when used on utility installation and maintenancevehicles which are subject to use on rough terrain where closure handlesoutwardly laterally-extended from the vehicle are liable to be severelydamaged or torn off. The invention herein is illustrated by a showingthereof in the accompanying drawings and description applied to autility vehicle door.

The instant improvement in flush panel construction locking-boltoperating structures can be utilized on both horizontal and verticaldoors, and also on double paneled or single paneled metal doors. Theinvention is illustrated in this specification as being applied to avertical door positioned on the right-hand side of a public utilitybody.

The invention herewith presented relates to improvements in theinvention presented in our application on Locking-Bolt OperatingStructures, Serial No. 5,245, filed January 30, 1948 (U. S. Patent No.2,637,585, issued May 5, 1953).

The annexed drawings and the following description present in detailcertain means illustrating our improvements in locking-bolt operatingstructures, the same describing and showing, however, only one form ofassembly in which the invention may be embodied.

In said annexed drawings:

Figure 1 is an outside elevation of a fragmentary part of a door orother closure for an opening into a compartment of a utility vehiclebody, in which closure our improvements in lockingbolt operatingstructures are incorporated, a fragmentary portion of the adjacentvehicle body in which the closure is mounted being also shown;

Figure 2 is a longitudinal, horizontal section, taken in the planesindicated by the line 2-2, Figure 1;

Figure 3 is a transverse, vertical section, taken in the plane indicatedby the line 3-3, Figure 1;

Figure 4 is a vertical, longitudinal section, taken in the planesindicated by the line 44, Figure 2; and

Figure 5 is a longitudinal, horizontal section, taken in the planesindicated by the line 5--5, Figure 4.

Referring to the annexed drawings in which the same parts are indicatedby the same several numbers in the respective views, a fragmentaryportion of a vehicle body is indicated by I, the same having a socket 2formed therein for the accommodation of the end of a slidable lookingbolt 3. The body I has an opening or a Wall compartment for which aclosure such as a door is provided. The door, in the design thereofshown for purposes of illustration in the accompanying drawings, is abox-like element having an outer wall 4, and is formed with a recessbreaking this outer wall 4, in which recess the instant improvements inlooking bolt operating structures are mounted.

Fitting the recess in the door is a cup-like liner or dished platestructure, Figure 3, having an inner base I, a side wall 8, and an outerperipheral flange 9, the latter abutting the outside face of the doorwall 4. The improved locking-bolt operating structure is mounted in thechamber 6 formed by and within the cup-like liner, Figures 2 and 5, andcomprises a vertical rotatable operating rod or pin [0 connected to theactuating means for the bolt 3, a mounting for this pin 10, and anoutside manually-actuable flanged panel secured to the pin l0 andserving as arflnger pull.

First describing the finger pull, it has a panel body I I whose exteriorface is substantially flush with the exterior face of the peripheralflange 9 of the liner, this panel body ll being disposed adjacent therear side of the chamber 6 and extending across about one half of thelatter and being slightly bent outwardly at its front edge to form acurved finger grip l2, Figures 2 and 5. This structure provides a fingerentrance 33 into the chamber 6 between the curved finger grip l2 and thefront part of the liner wall 8. The finger pull is also formed with endflanges l3 having holes l4 intersected by the bottom and tops ends ofthe pin 10 which pin ends are secured to the flanges [3 by welding themto the outside faces of the flanges l3, slightly spaced from the sidewall 8 of the liner, see 34, Figures 3 and 4.

The mounting for the pin it is a housing-like member, open at its innerside, as indicated by l5, Figure 2, and at its rear side, as indicatedby I5 and having a forwardly sloping front side member I6 formed with afront end flange I 6 welded to the base 1 of the liner. The housingmember is also formed with upper and lower 3 wings I! having flanges i8also welded to the base I of the liner.

The sloping front member [6 of the housing, at its rear side (9, iscurved in over the pin and lies a slight distance inwardly of the bodyll of the finger pull, as shown in Figures 2, 3, and 5. The rear end Hof the body ll of the finger pull extend somewhat beyond the rear end 19of the housing [6, i. e., substantially to the plane of the inner facesof the housing wings H, which plane is somewhat spaced from the rearside wall 8 of the liner. When the finger pull is actuated the rear endH of the finger pull body H plays in the space between the plane of therear edges of the wings I! of the pin housing and the rear side wall 8of the liner, as shown in Figure 5.

The wings I! furnish material for bearings 20 within which the pin I0 isjournalled adjacent its ends. Preferably, the bearings 20 are formed byextruding the material of the wings IT.

A lug 2| which has a cam-like action On the locking bolt 3, ashereinafter described, is secured adjacent one end to the pin I0 aboutmidway the length of the latter, and within the housing member, Figures2, 3, and 5. The lug 2| extends inwardly through an elongated slot 22 inthe base I of the cup-like liner, Figure 5, and also through acorresponding slot 26 in an abutting wearing plate forming a mountingfor a three-sided open-ended locking bolt housing 23. The housing 23 isformed with side flanges 24 which with the plate 25 are welded to theinside face of the base 1 of the cup-like liner.

The locking bolt 3 slides on the wearing plate 25 in, and through theopen ends of, the housing 23 for engagement in, and disengagement from,the socket 2 formed in the vehicle body I. The locking bolt 3 is formedwith a top recess 28 adjacent one side into which recess 28 the swingingend of the lug 21 extends in abutting position with an end wall of therecess 28. The opposite side of the bolt 3 is formed with a recess 29between an end wall of which and an abutment 21 struck up from thewearing plate 25 and extending into the recess 29 adjacent its oppositeend wall is a compression spring 30. i

From the aforegoing description it is evident that a pull outwardly uponthe member II will cause the lug 21 to retract the bolt 3 from thesocket 2 and that such action will compress the spring 30 which, uponrelease of the hand pull I I, will effect the return sliding movement ofthe bolt 3 to door-locking position, as clearly appears in Figures 2 and5.

The housing structure providing a mounting for the pin Ill preventsentrance of moisture and dirt to the pin chamber and, hence, through theslots 22 and 26, Figure 5, to the utility body.

The housing structure also provides spaces for the movements of the rearend of the finger pull and for the operating movements of the cam 21.The sloping character of the front member [6 of the housing gives moreroom for finger entrance into the space 33.

A key-operated lock 35 of the barrel type to prevent the opening of thedoor by actuation of the hand pull II is shown in Figures 1 and 2. Thereis secured to the rotatable barrel of the lock 35 one end of anelongated plate 32 having an angular end portion 35 forming an abutmentin the path of opening movement of the tail piece 3| of the bolt 3 ifthe barrel of the lock 35 is turned by the door key into lockedposition.

What we claim is:

1. A locking-bolt operating structure, for use with a closure having arecess breaking its surface, the combination therewith of a cup-likeliner seated in the recess and having a base, a side wall, and amarginal portion abutting the outer face of the closure, a housingstructure having a front wall mounted on and secured to the liner base,the housing structure also having opposed end walls, a pin rotatablymounted in the housing end walls, the housing having also an open innerside, bolt-actuating means connected to the pin and extended through theopen side of the housing, and a finger pull having an exterior surfacesubstantially flush with the marginal portion of the liner, the fingerpull having flanges extended into the liner and secured to the pinadjacent the respective ends of the latter.

2. A locking-bolt operating structure, characterized a in claim 1, inwhich bearings for the rotatable mounting of the pin are formed from theopposed housing end walls, and in which the respective ends of the pinare welded to the outside faces of the respective finger pull flanges.

3. A locking-bolt operating structure, characterized as in claim 1, inwhich the housing structure is open at the rear and is spaced at therear slightly forwardly of the rear of the side wall of the liner, andin which the rear end of the finger pull i curved inwardly in extendedformation to play in the space during the opening and closing movementsof the finger pull.
